CRITICAL E005: Suspicious download URL detected in skill instructions.

• Suspicious download URL detected (high risk: 0.90). Most URLs are PyPI, GitHub and Steam resources (low risk), but the prepare scripts fetch and execute remote installer scripts and download a Windows .exe from third-party domains (astral.sh and frippery.org), which are direct executable/script fetches and therefore present elevated risk.

MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).

• Third-party content exposure detected (medium risk: 0.30). At runtime, the skill indexes and searches C# PB script source code from the user’s installed Steam Workshop/local “Script.cs” files (Data/scripts.json inventory → index_scripts.py → cs_indexer.py reads each .cs file text), so outsider-authored script text can be ingested without the agent selecting a specific item first.

MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).

• Potentially malicious external URL detected (high risk: 1.00). The skill's prepare/install flow fetches and immediately executes remote installer scripts (https://astral.sh/uv/install.sh and https://astral.sh/uv/install.ps1) and downloads a remote BusyBox binary (https://frippery.org/files/busybox/busybox64u.exe) at runtime, which executes remote code and is required for preparation.
